I have an IDE hard drive in an enclosure powered by the mains and connected to my Mac Mini (running Tiger) by USB. The drive spins constantly whenever it has power, regardless of whether it's mounted or any read/write is taking place. I'd like it to only spin when I'm accessing it and to spin down after say 5 mins activity or the Mac goes to sleep. Any ideas? Like I say this is a 3.5 inch IDE drive in an enclosure I bought separately. Cheers.
